GAS-BURNER;

SPECIFICATION forming part of Letters Patent No. 756,155, dated March 29, 1904. Application filed December 18, 1896. Renewed August 11,1903. -Seria1No. 169,080 (No model.)

To all whom it may concern:

Be it known that I, HENRY BRYANT, a citizen of the United States, and a resident, of Aransas Pass, inthe State of Texas, have invented a new and useful Improvement in Gas- Burners, which is made and used substantially,

as set forth hereinafter and as shown in, the accompanying drawings, in which Figure 1 is anelevation of the burner as in use. Fig.- 2 isthe same in section.

The object of this invention is to produce a burner suited to produce an illuminating-flame ofacetylene gas and to use the same for such purpose; and the invention consists in forming a burner with two jet branches with outlets at a suitable distance apart andprojecting from them for burning, so that jets of gas will issue and gather about them an envelop of air carried along and strike together at an angle of nearly ninety degrees and spread into a beautiful flame in burning, and in Various details to facilitate the manufacture and use of same.

Fig. 1 shows an external view, and Fig. 2 a

sectional view, of a burner made with-these improvements in one form. The base B is made to attach to a branch of a service-pipe A and has within it a chamber or space for a body of loose cotton C or other suitable material for checking the flow of gas and reducing its pulsations to auniform motion. From this chamber spread two arms Dat an angle of about eighty degrees or thereabout. These arms D are arranged so that they can be bored out with small drills, which will go inside .of-

the lower edge of the base B, as illustrated in dotted lines in Fig. 2. At suitable distances the arms D bear cross-tubes E at such angles that their upper ends will approach each other at an angle of about ninety degrees. The cross-tubes E are arranged to be bored out with small drills from the outer ends, using very fine calibers for the jet-outlets at the upper ends and larger for the outer portions, into which are set-screws H to close the tubes. The tubesE are arranged at suitable distances apart, so as to gather about the jets of gas envelops of air carried with the gas smoothly and so that when they reach a proper point they will strike together fairly and spread into a beautiful flame F from the gas and air carried with it in burning. The'ends of the burner-arms E E are made conical at their ends and'have round outlet-holes for the gasjets, arranged to carry air by frictional contact as a moving envelop, so as to cause mixture for thorough combustion by the two jets and their envelops striking and minglingtogether at a distance from the burner-points, so as ,to prevent deposit ofcarbon on the points and so the air will sweep away any chance deposit. The extreme sharp ends of the cones around the outlet-holes are cutoff, so

the air passing along them to envelop the gas will come in contact just beyond the end to avoid inducing a carbon deposit thereon. The

gas is thus emitted from the two burner-tips 7 having circular tapering orifices, so as to form fine jets of gas tending to form inverted cones directed obliquely upward toward each other so as to impinge on each other at a considerable distance above the tips to form a flame out of contact with the substance of the tips, so as to form a clearance-spacebetween the orifices and extending a distance below them, and so that a current of air will be drawn by suction along each of the tips, so as to sweep the conical point of the tip from any chance deposit thereon.

Various modifications may be made in this. Fig. 3' shows one such, in which the arms D bear elbow-joints D and these bear burnertips E, with holes in their ends arranged to throw gas-jets to meet at the proper distances and angles to form the flame.

I claim- 1. In an acetylene-gas burner having abody B with arms D bearing tubes with small externally-truncated conical tips with round outlets in their ends at a distance apart, formed soas to leave a surface at the extreme end of the tip between the orifice and the outer tapering walls, arranged todeliver jets of gas which will gather envelope of air about them and strike together at an angle of near ninety degrees for burning. ii

2. A burner for acetylene gas, having two branches set at an angle to each other with externally-truncated conical points, formed so as to leave a surface at the extreme point between the orifice and the outer tapering walls, arranged to throw jets of gas together for burning at a distance from said points, and draw a current of air converging to the end of each cone, to prevent deposit of carbon on the tips.

3. In a burner the combination of two burner-tips, having externally-truncated conical ends, formed so as to leave a surface at the extreme end of the tip between the orifice and the outer tapering walls, arranged obliquely upward and each having an exceedingly-small orifice opening from its apex, the tips being directed toward each other whereby the jet of gas emitted from each tip impinges upon the other jet at a considerable distance above the tips to form the luminous flame out of contact with said tips and little surface is formed at the tips to heat the gas as it emerges and receive deposits of carbon.

4:. In a burner the combination of two burner-tips having externally-truncated conical ends, provided with small apertures opening through the apexes of said conical ends, formed so as to leave a surface at the extreme end of the tip between the orifice and the outer tapering walls, arranged obliquely upward and directed toward each other, whereby all of the jet of gas emitted from each tip impinges upon the other jet at a considerable distance above the tips to form the luminous flame out of contact with said tips and pre vent carbon deposit, and a clearance-space is formed between the orifices of the burner-tips and extending to some distance below them.

5. An acetylene-gas burner having a body with arms bearing tubes with small externallytruncated conical tips with round outlets in their ends, set a distance apart, formed so as to leave a surface at the extreme end of the tip between the orifice and the outer tapering walls, and arranged to deliver jets of gas which will gather envelops of air about them and strike together at an angle of near ninety degrees for burning, substantially as set forth.

6. In a burner the combination of two.

burner-tips having externally-truncated conical ends provided with small apertures opening through the apexes of said conical ends, formed so as to leave a surface at the extreme point between the orifice and the outer tapering walls, arranged obliquely upward and directed toward each other whereby all the jet of gas emitted from each tip impinges upon the other jet at a considerable distance above the tips to form the luminous flame out of contact with said tips and prevent carbon deposit, and a clearance-space is formed between the orifices of the burner-tips and .extending some distance below them.
